请教诸位NN：）

Growing competitive pressures may be encouraging auditors to bend the rules in favor of clients; auditors may, for instance, allow a questionable loan to remain on the books in order to maintain a bank’s profits on paper.

(A) clients; auditors may, for instance, allow

(B) clients, as an instance, to allow

(C) clients, like to allow

(D) clients, such as to be allowing（A）

(E) clients; which might, as an instance, be the allowing of

请教诸位NN，如果是

  （F）clients, for instance, to allow

可以么？

不可以

F. Pressure may be encouraging auditors to bend rules in favor of clients to allow a loan to remain on books.

谁是to allow的逻辑主语呢 auditors, clients, rules?

很多很多谢谢给joe11：）

不过，对于此题我还想与你商量一下，呵呵

for instance 是举例，所以to allow a loan to remain on books是to bend rules in favor of clients的一种。

故，我理解的F是 Pressure may be encouraging auditors to allow a loan to remain on books.

encourage sb. to do sth 中 to do 的逻辑主语是sb. 在F中，to allow 的逻辑主语就是auditors

还请joe11大侠和其他诸位侠客们帮我看看其他问题吧，

这里的关键在于 for instance 的用法。

我认为，for instance, 放在句中时，是插入语，其前后的内容相关联组成完整句子。如 A. 和：

We need to rethink the way we consume energy. Take, for instance, our approach to transport. （Longman)

Canada, for instance, is mounting the biggest security operation in its history this weekend to stop activists disrupting the Summit of the Americas in Quebec. (BBC)

Alaska, for instance, receives $6.60 for every dollar paid in federal gas taxes. (USA Today)

不排除有人用for instance 前后不加逗号的。

Here's a for-instance that happened to me in Jackson" (Jean Anderson)

So for instance I might say I’ll need another three days to finish the work.（BBC)

如果For instance,放在句首，表示整句话都是上文的例子时，to allow 动词不定式可以做主语。

'There are a number of rules you must abide by. For instance, you may not use the swimming pool unsupervised.' (BBC)

Conclusion: 还是 A.好。
